I recently bought my first pH meter - a Hanna Checker, Model HI98103 <details here> Mine is the newer model, and accuracy is +/- 0.2 pH. I am using it for both juice/must/wine and TA (total acid) titrations. My model is capable of either one-point or two-point calibration. Hanna provides...

I recently bought a pH meter, and I am finding it to be very useful! But one quick question about using it on actively fermenting wine: Do I need to worry about CO2 affecting my reading? I seems like I remember reading somewhere that CO2 should be removed by heating/agitation before trying to...

I have been making wine for years, but this my first-ever wine from my Cynthiana grapes, and also my first attempt at malolactic fermenation (MLF). After 3 days fermentation on the pulp, I pressed, then added Wyeast Malolactic culture Blend 4007. That was almost 9 days ago. Today there is...

I have decided I need a pH meter asap. It would be great if I could buy one locally rather than waiting for an online order. I live in a medium size city in SW Missouri (population is about 160,000) - but I don't know what kind of local business might sell pH meters. Are pH meters used to...

Is it necessary to pre-heat must from Norton/Cythiana grapes before acid testing to get accurate results? Do most wine makers consider this to be a commonly accepted practice? I came across this suggestion in a paper called "Growing and Vinting Cynthiana/Norton Grapes" presented by Dr. Gary...
